Are the Mavs going to trade anyone to get a solid big man who can defend the post and score a little?

I know Okafor was traded recently but I think if the Mavs got Okafor they would be a nba championship contender. They need a solid big man that can defend and score a little. I would be willing to trade Terry, Kidd, Marion, and Howard for him. Not all those players for just him but yeah.
